A chemical detector is provided and includes a chemical detector device and a chemical agent aerosol vaporizer assembly. The chemical agent aerosol vaporizer assembly includes a vaporizer fluidly interposed between an inlet and an outlet and is configured to receive via the inlet a chemical agent aerosol in the vaporizer wherein the chemical agent aerosol is smeared against a fluted surface that is passivated against adsorption and vaporized. The vaporized chemical agent aerosol is subsequently output to the chemical detector device via the outlet.
